Which Protectstar Android Apps Do Collect Personal Data?

At Protectstar, we put your privacy at the forefront of what we do and only collect necessary information to provide our products and services effectively.

Which Protectstar Android Apps Do Collect Information?

  • Anti Spy Android
  • Antivirus AI Android
  • Camera Guard Android
  • DNS Changer Android
  • Firewall AI Android
  • Micro Guard Android
  • iShredder Android (only if you use a MY.PROTECTSTAR account)

Note about the Firewall AI app:

The Firewall AI app forwards the traffic of allowed connections directly to their destination through the Android VPN Service without using a remote VPN server. Its mode of operation can lead to one of two scenarios concerning your internet traffic:

  • When IP Filtering is Disabled: Any blocked internet traffic is routed into the local VPN service, effectively acting as a sinkhole that drops all blocked traffic.
  • When IP Filtering is Enabled: Both blocked and allowed internet traffic are routed into the local VPN service, but only allowed traffic is forwarded to the intended destination. No traffic is sent to a remote VPN server.

The Android VPN Service ( is utilized to locally route all internet traffic to Firewall AI. This design means that root access is not required to build or implement this firewall application.

Through transparently explaining these functions, we aim to instill confidence in our users regarding the privacy and integrity of their data when utilizing our Firewall AI applications.

Why do we process your data?

When you use our Protectstar® apps, we collect certain information to enhance the security and functionality of our services. Here’s why we need specific types of data:

  1. App Package Name: Users’ installed application information. We collect the names of apps installed on your device. This helps us identify which apps are running and enables us to tailor our security measures to the specific apps you use. It's a crucial step in ensuring that our security protocols are effective against threats that might target specific applications.
  2. SHA-256 & MD5 Checksum: These are unique digital fingerprints of an app's APK file. By collecting these checksums, we can verify the integrity of the apps on your device. This is essential for detecting alterations or corruptions in app files that could indicate the presence of malware or spyware.
  3. File Checksums: Similar to the app checksums, we collect SHA-256 and MD5 checksums of files on your device. This allows us to verify the integrity of these files and detect any unauthorized modifications. It’s a vital component in our effort to safeguard your device from malware that might alter or damage your files.

The purpose of sending users’ installed application information, the calculated SHA-256/MD5 checksums to and to is to analyze the information by our Protectstar® Artificial Intelligence Cloud (AI Cloud).

Operating on servers, rather than individual devices, the AI Cloud offers efficient, precise analysis without taxing your device's resources.
